Processed TESS flux gives 99.2 to 112.5 effective days for 1500 ppm test dips in KIC 3542116

We tested seven TESS-SPOC sectors of KIC 3542116, also named TIC 122519163. Six fixed shapes use parameters from reported Kepler dust-tail events, with stated limb darkening assumptions. We searched binned PDCSAP flux with local quadratic fits. The accepted grid represents 116.479 days. No dimming or brightening passes the fixed score threshold of 7; the largest dimming score is 3.860. The score is an empirical measure, not a Gaussian significance. Added 1500 parts per million dips give 99.167 to 112.542 effective days, depending on shape. Added 500 ppm dips give only 0.521 to 4.271 days. All 3000 ppm tests are recovered on the accepted grid. A quarter-bin phase check changes aggregate effective time by at most 0.271 day. An extra search of TESS-SPOC and QLP aperture flux gives three dimming groups and three brightening groups. We preserve these features for product and background checks. None is a confirmed transit. The main result measures recovery after archive correction and binning. It cannot measure signals removed in those steps or establish a change in comet activity. The package contains 14 source FITS files, source hashes and URLs, complete trial results, figures, code, and independent direct-fit checks.
